The R&S®CBT performs Bluetooth® RF tests at extremely high speed. In addition to power, modulation, frequency and BER tests, the R&S®CBT carries out a variety of spectrum measurements without requiring any extra spectrum analyzers. While conventional Bluetooth® testers sequentially measure power, modulation, frequency accuracy and also frequency drift, the R&S®CBT performs all these measurements in a single test cycle, which makes the instrument very fast in production applications. For use in the lab, the R&S®CBT offers traces for power, modulation and spectrum, which are output in realtime on a large graphical display.
